A brief history of Java
– "Java, whose original name was Oak, was developed as a
part of the Green project at Sun. It was started in
December '90 by Patrick Naughton, Mike Sheridan and
James Gosling and was chartered to spend time trying to
figure out what would be the "next wave" of computing and
how we might catch it. They came to the conclusion that at
least one of the waves was going to be the convergence of
digitally controlled consumer devices and computers. "

Why Java?

7. Java Basics 7

8. Java Basics 8
This year Java grew by around 6% compared to last
January, which was right around 62,000 job postings at the
time.
Java is just about to celebrate its 24-year birthday, and as a
programming language, it has definitely stood the test of
time.
Java was developed by a Canadian computer scientist that
used to work with Sun Microsystems, James Gosling.
It’s a language that lets developers “write once, run
everywhere,” (WORA), which mean its compiled code, also
known as bytecode, can run on almost any platform without
recompilation.

9. Java Basics 9
How Java Works
Java's platform independence is achieved by the
use of the Java Virtual Machine
A Java program consists of one or more files with a
.java extension
– these are plain old text files
When a Java program is compiled the .java files
are fed to a compiler which produces a .class file
for each .java file
The .class file contains Java bytecode.
Bytecode is like machine language, but it is
intended for the Java Virtual Machine not a specific
chip such as a Pentium or PowerPC chip

10. Java Basics 10
More on How Java Works
To run a Java program the bytecode in a .class file
is fed to an interpreter which converts the byte code
to machine code.
Some people refer to the interpreter as "The Java
Virtual Machine" (JVM)
The interpreter is platform specific because it takes
the platform independent bytecode and produces
machine language instructions for a particular chip
So a Java program could be run an any type of
computer that has a JVM written for it.
– PC, Mac, Unix, Linux, BeaOS, Sparc

11. Java Basics 11
A Picture is Worth…
The Interpreter's are sometimes referred to as the Java Virtual
Machines
The output of the
compiler is .class
file

12. Java Basics 12
So What!
The platform independence of Java may be a huge
marketing tool, but is actually of little use to people
learning Object Oriented Programming and
Abstract Data Types
What is of use is the simplicity of the Java syntax
and programming concepts
Java is a "pure" Object Oriented Language
– encapsulation, inheritance, and polymorphism
– all code must be contained in a class
– no free functions (functions that do not belong to some
class) like C++, although someone who wants to write
messy Java code certainly can
– Is OO the best programming paradigm?

HelloWorld.java
/**
* A simple program
*/
public class HelloWorld
{
public static void main(String[] args)
{
System.out.println("Hello World!");
}
}

How to make Java as a hobby?
Start from Simple.
Co-Related it to day to day life.
Make third eye open and think beyond limit.
Once Start , Finish any how !
Momentum slow but steady.
Step - by- Step (one at a time ).
Never Shy to asked Question or queries.
Achieved little and enjoy yourself.
Practise. Practise. Practise !!!
